Abstract

The invention provides a printing apparatus where, in a case where skew with regard to the transport direction is not detected in a medium, it is possible to shorten the time from starting of an operation for detecting skew to starting recording with regard to the medium. In order for skew relative to the transport direction to be detected in a sheet (P) which is transported to a recording unit (28), a carriage (18) is initially moved in a scanning direction to a first position and the sheet (P) is transported in this state. Then, when the front edge of the sheet (P) in the transport direction is detected by a second sensor (75), the carriage (18) is moved in a direction so that the second sensor (75) is no longer able to locate the front edge to a second position, which is separated from the first position by a regulating movement distance. Furthermore, the sheet (P) is transported to where the second sensor (75) locates the front edge of the sheet (P) in the transport direction at the second position and skew in the sheet (P) is detected based on this transport distance and the regulating movement distance.

Description

Printing equipment

Technical field

The present invention relates to printing equipment.

Background technology

Printing equipment possesses for recording the recording unit of (printing) and the delivery section to this recording unit pumped (conveying) medium to sheet medium.The balladeur train of the scanning direction movement that can intersect along the throughput direction with medium is provided with in the recording unit of this device.The record head that can record the medium being transported to recording unit is provided with at this balladeur train.In this printing equipment, by delivery section, medium is carried to recording unit, and make balladeur train suitably mobile printing to medium carrying out being completed by record head along scanning direction.Medium after such printing terminates is discharged by the downstream of delivery section to recording unit.

In addition, the high-precision printing for medium such as the 3D printing printing of stereos copic viewing (can) is sometimes required to carry out in recent years.In this situation, avoid producing medium just very important relative to the diagonal (skew, deflection) of throughput direction.Suppose to print under the state of the diagonal that there occurs medium, then may depart from from correct position relative to the printing position of medium.Especially, just must use the dedicated medium of high price to carry out 3D printing, if to have carried out in incorrect position relative to this medium printing and cannot stereos copic viewing, dedicated medium at high price will be consumed in vain.Therefore, can consider that the technology applying patent document 1 is to detect the diagonal of medium relative to throughput direction, and discuss countermeasure based on the detection of this diagonal.

In addition, in patent document 1, the diagonal of medium relative to throughput direction is detected as follows.That is, be provided with the sensor that can detect the end of medium at balladeur train, and detected the position at the two ends, scanning direction of separate in the conveying direction two positions of medium by this sensor respectively.Specifically, under the state that stopped the conveying of this medium when medium reaches recording unit, make the overall width round trip of balladeur train on the scanning direction of medium and detect the position at the two ends, scanning direction of the medium of first position.Afterwards, after predetermined amounts pumped (conveying) medium, stop this conveying, and make balladeur train detect the position at the two ends, scanning direction of the medium of second position as described above along scanning direction round trip in this condition.Then, based on the position at the two ends of the scanning direction of above-mentioned two positions of medium, the diagonal relative to throughput direction of this medium is detected.

Patent document 1: Japanese Unexamined Patent Publication 2009-6580 publication

By applying the technology of patent document 1, can the medium be transferred to recording unit be detected relative to the diagonal of throughput direction.But, if will start when the diagonal of medium not detected, this medium is printed (record), then from play start printing for the work of the diagonal detecting medium till, cost long time.This is because the reason of (1) and (2) below.

(1) in order to detect the position at the two ends, scanning direction at separated in the conveying direction two places of medium respectively, the whole width of balladeur train on the scanning direction of medium must be made to add up to carry out two to come and go, it is elongated to do the required time like this.

(2) in order to do not detect medium diagonal, start the printing (record) carried out medium after for the end-of-job of this detection, medium must be made to move to the direction contrary with throughput direction and make the front end of the throughput direction of this medium get back to than the position of recording unit by the upstream of this throughput direction, therefore spending the extra time.

Summary of the invention

The object of this invention is to provide printing equipment, it is not when the diagonal of medium relative to throughput direction being detected, can shorten from play the time till starting to record medium for the work of the detection of this diagonal.

Below, be just described for the technical scheme that solves the problem and action effect thereof.

The printing equipment solved the problem possesses: delivery section, and it carries this medium to the recording unit recorded the medium of sheet; Balladeur train, it is arranged at recording unit, and the scanning direction that can intersect along the throughput direction relative to the medium determined by delivery section is moved; Sensor, it is arranged at balladeur train, can detect with or without medium; Control part, it controls the work of delivery section and balladeur train; And test section, it detects the diagonal of medium relative to throughput direction.And above-mentioned control part, as detecting the work of medium relative to the diagonal of throughput direction, makes delivery section and balladeur train work as follows.Namely, above-mentioned control part, balladeur train is made to move till the 1st position that the front end of the throughput direction of medium can be detected by sensor, in this condition, if the front end of the throughput direction of the medium carried to recording unit by delivery section is detected by sensor, balladeur train is then made not detect that the direction of above-mentioned medium moves to from the 1st position by the 2nd position that the amount of regulation displacement is left along sensor, until sensor till the 2nd position detects the front end of the throughput direction of medium, this medium is carried by delivery section.In addition, above-mentioned test section, based on to detect from sensor in the 1st position the front end of the throughput direction of medium play this sensor till the 2nd position detects the front end of the throughput direction of medium, the fed distance of medium of being carried by delivery section and afore mentioned rules displacement, detect the diagonal of this medium relative to the throughput direction of medium.

According to said structure, the distance on the balladeur train scanning direction between the 1st position and the 2nd position is for specify displacement, and this regulation displacement can be set as, the value shorter than the distance of the overall width on the above-mentioned scanning direction of medium.By setting regulation displacement like this, balladeur train moves the required time and shortens from the 1st position to the 2nd position.And then, when the state lower sensor that balladeur train has been displaced to the 2nd position detects the front end of the throughput direction of medium, when the diagonal of this medium relative to throughput direction not detected, can from the position of medium now by this medium to downstream conveying record.In addition, even if need to make medium return throughput direction upstream side until record start position, now medium round about (throughput direction upstream side) conveying capacity seldom.By such scheme, when the diagonal of medium relative to throughput direction not detected, can shorten and play the time till starting to carry out the record of medium from the delivery section of the detection for carrying out this diagonal and the work of balladeur train.

In addition, above-mentioned control part, preferred: by sensor after the 1st position detects the front end of the throughput direction of medium, balladeur train is moved to the side of scanning direction, when detecting above-mentioned medium by sensor at this moment, the moving direction of this balladeur train is reverse, when above-mentioned medium not detected by sensor, carry out the movement of the balladeur train of the amount of afore mentioned rules displacement.

When making above-mentioned balladeur train move to the 2nd position from the 1st position in a scanning direction, the balladeur train being in the 1st position is made to move to the direction contrary with the 2nd position at first sometimes.When medium is relative to throughput direction diagonal, balladeur train also detects medium by sensor after starting movement to the direction contrary with the 2nd position at this moment.Control part, when detecting medium by sensor like this, make the moving direction of balladeur train oppositely, make this balladeur train towards the 2nd position.Thus, even if make above-mentioned balladeur train move from the 1st position to the direction contrary with the 2nd position, oppositely towards the 2nd position, the diagonal of medium also can be detected by making the moving direction of balladeur train.In addition, when making balladeur train move from the 1st position to the direction contrary with the 2nd position, when detecting medium by sensor, if make the moving direction of balladeur train immediately oppositely, make this balladeur train towards the 2nd position, then can suppress the meaningless movement of balladeur train when moving from the 1st position to the 2nd position as far as possible.

In addition, above-mentioned control part is preferably configured to, when detecting the diagonal of medium by above-mentioned test section, so that this medium is made delivery section work to the mode that throughput direction is discharged.

According to above-mentioned formation, the diagonal of medium attend the meeting greatly the degree of obstacle causes to the record for this medium time, this medium can be discharged to throughput direction.Therefore, it is possible to avoid the situation recording, cause thus consuming in vain medium to the medium of diagonal.In addition, because this medium is discharged to throughput direction when detecting the diagonal of medium, so the printing equipment of the structure not making medium to the direction movement contrary with throughput direction also can be applied to.

In addition, above-mentioned control part is preferably configured to, and when being detected the diagonal of medium by test section, makes delivery section perform the diagonal removal work of the diagonal for eliminating medium.

According to above-mentioned formation, even if medium generation diagonal, also by diagonal removal work, this diagonal can be eliminated, start subsequently to carry out the record for this medium, so the medium of diagonal can be discharged and save the man-hour reapposed.

Above-mentioned control part is preferably configured to, being need to carry out the medium of high accuracy record or do not need to carry out the medium of high accuracy record corresponding to the medium carried to recording unit, determining whether to perform for detecting the delivery section of medium relative to the diagonal of throughput direction and the work of balladeur train by test section.That is, above-mentioned control part, when the medium carried to recording unit is the medium needing to carry out high accuracy record, performs and is used for detecting the delivery section of medium relative to the diagonal of throughput direction and the work of balladeur train by test section.On the other hand, above-mentioned control part, when the medium carried to recording unit is the medium without the need to carrying out high accuracy record, does not perform for detecting the delivery section of medium relative to the diagonal of throughput direction and the work of balladeur train by test section.

According to above-mentioned formation, when the medium carried to recording unit is the medium needing to carry out high accuracy record, medium for when becoming problem the record carried out for this medium, can perform the work for the delivery section and balladeur train detecting this diagonal relative to the diagonal of throughput direction.On the other hand, when the medium carried to recording unit is the medium without the need to carrying out high accuracy record, medium for when not being problem the record carried out for this medium, can not carry out the work for the delivery section and balladeur train detecting this diagonal relative to the diagonal of throughput direction.Therefore, the detection of medium relative to the diagonal of throughput direction can be performed necessarily, can only have and just perform where necessary.In addition, the detection of medium relative to the diagonal of throughput direction can be performed necessarily, therefore also can not occur: make with this unnecessary execution until start elongated situation of spent time to the record of medium.

In addition, above-mentioned printing equipment, preferably, also possesses support portion, this support portion supports described medium and has the male and fomale(M&F) formed by the multiple protuberances arranged along described scanning direction, and described 1st position is set as with described 2nd position the position that the shape of described male and fomale(M&F) on described scanning direction is identical respectively.

According to this formation, the 1st position and the 2nd position are set to the identical position of the shape of the male and fomale(M&F) on the moving direction of balladeur train in support portion.Therefore, the light volume reflection being incident in sensor in the identical position reflection of the shape of male and fomale(M&F) is equal extent in the 1st position and the 2nd position.Therefore, it is possible to suppress the situation that the accuracy of detection of diagonal lowers because of following reason: the variform position being mapped to male and fomale(M&F) in the illumination of the 1st position and the 2nd position sensor, causes the light income of sensor different, cause its output valve to have deviation thus.

In above-mentioned printing equipment, preferably, described control part obtains the reference position of described balladeur train by abutting, described balladeur train is moved to described reference position for benchmark and predetermined described 1st position and described 2nd position, thus is located on described scanning direction by described balladeur train.

According to this formation, control part obtains the reference position of balladeur train by abutting, and is that benchmark makes balladeur train move to predetermined 1st position and the 2nd position, thus carries out balladeur train location in a scanning direction with reference position.When sensor being configured at the 1st position and the 2nd position, no matter when sensor can be configured at the position that the shape of male and fomale(M&F) is identical.

And then, in above-mentioned printing equipment, preferably, described control part, the position that the shape that described support portion is detected on described male and fomale(M&F) by described sensor without making described balladeur train move under the state of described medium is identical, obtains described 1st position and described 2nd position that should configure described sensor based on this position detected.

According to this formation, control part, support portion detecting the identical position of the shape of male and fomale(M&F) without making balladeur train move under the state of medium by sensor, obtaining the 1st position and the 2nd position of answering sensors configured based on this testing result.Therefore, even if cause the position of male and fomale(M&F) to have deviation in a scanning direction due to the assembling deviation etc. of support portion, also comparatively sensor can be configured at the 1st position and the 2nd position.

In above-mentioned printing equipment, preferably, described 1st position and described 2nd position are set to the position on the end face of described protuberance.

According to this formation, the 1st position and the 2nd position, as the identical position of the shape of male and fomale(M&F), are all set as the position on the end face of protuberance.Such as, in bottom ink liquid delay, flowing etc. because the impact of black liquid makes light reflectivity easily change, but be set with the end face of the protuberance of the 1st position and the 2nd position, its light reflectivity is more stable, can reduce the error detection of diagonal.

In addition, in above-mentioned printing equipment, preferably, described 1st position and described 2nd position are set to: specify that the reverberation of light in the multiple face of the shape of described male and fomale(M&F), that irradiate from described sensor is by the position the minimum face of the light income of this sensor institute light.

According to this formation, 1st position and the 2nd position are set to, the reverberation of the light irradiated from sensor is by the position the minimum face of the light income of this sensor institute light, so can make until the output of sensor exceedes threshold value, the medium conveying capacity entered in the luminous point of sensor becomes many relatively, the ratio of occupying of medium in the luminous point of sensor becomes large relatively.Therefore, even if due to the assembling deviation etc. of such as support portion, the position of the sensor configured in the 1st position and the 2nd position is departed from from the position of the supposition male and fomale(M&F) a little to scanning direction, because the male and fomale(M&F) in luminous point to occupy ratio relatively little, so, relatively can reduce the impact caused by the deviation of male and fomale(M&F).Thus, depart from comparatively speaking by this position, the error detection of diagonal can be reduced.

And then in above-mentioned printing equipment, preferably, on described scanning direction, the spot diameter being irradiated to the light of described male and fomale(M&F) from described sensor is wider than the width of described end face.

According to this formation, sometimes, due to the attachment of such as medium bits (such as paper scrap) or ink mist etc., the certain surface local of the detected object on male and fomale(M&F) produces the position of light reflectivity exception.Even if under these circumstances, in the luminous point at this abnormal position to occupy ratio relatively little, so, the error detection of the diagonal caused by this abnormal position can be reduced.

In addition, controller 70 has: during when making delivery section 27 work by the control to conveying motor 33 and by making balladeur train 18 work to the control of carriage motor 40, as the function of the control part controlled the work of these delivery section 27 and balladeur train 18.In other words, then controller 70 possesses the control part 70a played a role as described above.In addition, controller 70 is also possessed and detects the test section 70b of this paper using P relative to the diagonal of throughput direction when being carried to recording unit 28 by paper using P by delivery section 27.

Fig. 3 ~ Fig. 6 illustrates the movement for the delivery section 27 (paper using P) and balladeur train 18 detecting above-mentioned diagonal.

When being carried to recording unit 28 by paper using P by delivery section 27 to print paper using P, controller 70 makes balladeur train 18 mobile till the 1st position P1 along scanning direction (arrow X1, X2) as shown in Figure 3.1st position P1 be can by the 2nd sensor 75 detect the front end of the throughput direction of above-mentioned paper using P position, be specifically the position corresponding with the substantial middle of the above-mentioned scanning direction of paper using P.In addition, in printing equipment 11 preferably, adopt: the central authorities of scanning direction of paper using P carried to recording unit 28 and the size of paper using P have nothing to do the structure of the certain position always configured in a scanning direction.Therefore, the size of the 1st position P1 and paper using P in this embodiment is irrelevant always certain.

Under the state that balladeur train 18 is moved to the 1st position P1, if carry paper using P by delivery section 27, then the front end of the throughput direction (arrow Y-direction) of paper using P arrives the position corresponding with the 1st sensor 74 close to recording unit 28.Now, above-mentioned front end is detected by the 1st sensor 74.Controller 70 based on the front end of the throughput direction of the paper using P detected by the 1st sensor 74 position and hold that after this conveying proceeds time the position of paper using P.And, proceed in the conveying of paper using P, when the front position of the throughput direction of paper using P is corresponding with the 2nd sensor 75 as shown in Figure 4, above-mentioned front end detected by the 2nd sensor 75.Then, controller 70, based on this situation of the front end throughput direction of paper using P being detected by the 2nd sensor 75, stops the conveying of the paper using P undertaken by delivery section 27, and balladeur train 18 is moved till the 2nd position P2 shown in Fig. 5.

2nd position P2 be along Fig. 4 arrow X1, X2 shown in scanning direction in the 2nd sensor 75 do not detect above-mentioned paper using P direction (in this embodiment for arrow X1 direction), balladeur train 18 is left from the 1st position P1 by the amount of regulation displacement x after position.In addition, regulation displacement x is set to following values: and balladeur train 18 shorter than the distance from the end of the scanning direction of the 1st position P1 to paper using P (being the end in arrow X1 direction in this embodiment) is as much as possible close to the value of above-mentioned end.About such regulation displacement x, preferably, the information that the printing condition contained by the print job data sent from host apparatus 71 is correlated with holds the size of paper using P, correspondingly sets with the size of the paper using P of this assurance.

And, under the state making balladeur train 18 be moved to the 2nd position P2, if carry paper using P by delivery section 27, then, when the front position of the throughput direction of paper using P is as shown in Figure 6 corresponding with the 2nd sensor 75, above-mentioned front end detected by the 2nd sensor 75.Controller 70 (test section 70b) is obtained: from by the 2nd sensor 75 the 1st position P1 detect above-mentioned front end to above-mentioned front end being detected at the 2nd position P2, carried the distance (hereinafter referred to as fed distance y) of paper using P by delivery section 27.This controller 70, based on this fed distance y and afore mentioned rules displacement x, detects the paper using P that carries to recording unit 28 relative to the diagonal of throughput direction.And controller 70, carries out the printing to paper using P when the diagonal of paper using P not detected in recording unit 28, and the paper using P after printing is discharged to stacker 23.On the other hand, controller 70, when detecting the diagonal of paper using P, does not carry out, to the printing of paper using P, this paper using P is sent to throughput direction downstream in recording unit 28, thus paper using P is discharged to stacker 23.

Next, the effect with regard to printing equipment 11 is described.

When requiring to carry out the high accuracy printing that 3D printing waits for paper using P, if print under the state that there occurs diagonal relative to throughput direction at paper using P, then may depart from from correct position relative to the printing position of paper using P.Especially, when 3D printing etc. needs paper using P to be set to special high price paper using, print paper using P if deviate from from tram, this paper using P is consumed in vain, and this is the problem that can not be ignored.In order to tackle such situation, the paper using P that subtend recording unit 28 is carried detects relative to the diagonal of throughput direction, and is not discharged by this paper using P with printing paper using P based on detecting of this diagonal.But, produce following problem according to the method for the detection of above-mentioned diagonal: when this diagonal not detected, when starting to print paper using P, from play start printing for the work of the diagonal detecting paper using P till, take a long time.

So, in the printing equipment 11 of present embodiment, detect the diagonal of paper using P as follows.That is, when detecting the diagonal of paper using P, balladeur train 18 being moved until the 1st position P1, and in this condition paper using P being carried to recording unit 28.And, if detected the front end of the throughput direction of paper using P by the 2nd sensor 75, then do not detect that the direction of above-mentioned paper using P makes balladeur train 18 move to the 2nd position P2 left by the amount of regulation displacement x from the 1st position P1 along the 2nd sensor 75.And then, until the front end of the throughput direction of paper using P detected at the 2nd position P2 the 2nd sensor 75, carry this paper using P by delivery section 27.The controller 70 of printing equipment 11 is obtained: to be detected by the 2nd sensor 75 at the 1st position P1 the front end of the throughput direction of paper using P to the front end of the throughput direction of paper using P being detected at the 2nd position P2 by the 2nd sensor 75, carried the fed distance y of paper using P by delivery section 27.And, based on this fed distance y and afore mentioned rules displacement x, detect the diagonal of paper using P relative to throughput direction.

Here, the 1st position P1 and the distance of the 2nd position P2 on the scanning direction of balladeur train 18 are for specify displacement x.About this regulation displacement x, the value shorter than the distance of the whole width on the scanning direction of paper using P can be set as.By setting regulation displacement x like this, making balladeur train 18 move the required time from the 1st position P1 to the 2nd position P2 and shortening.And then, when detecting the front end of the throughput direction of paper using P by the 2nd sensor 75 under the state that balladeur train 18 has been displaced to the 2nd position P2, when the diagonal of this paper using P relative to throughput direction not detected, can print by recording unit 28 to downstream conveying from the position of paper using P now by this paper using P.In addition, even if need paper using P to be returned throughput direction upstream side till printing starting position, paper using P is now minimum to the conveying capacity of opposite direction (throughput direction upstream side).By such scheme, when the diagonal of paper using P relative to throughput direction not detected, can shorten and play the time till the printing of paper using P is started from the delivery section 27 of the detection for diagonal and the work of balladeur train 18.

Fig. 7 illustrates that the paper using P detecting and carry to recording unit 28 is relative to the flow chart of the step of the diagonal of throughput direction.

If supply paper using P from feed cassette 16 in the process of the step 101 (S101) of this figure, then the process as S102 makes balladeur train 18 move to the 1st position P1.And then, as the process of S103, judge whether the front end of the throughput direction of the paper using P carried by delivery section 27 is detected by the 1st sensor 74.If be affirmative determination here, then the position of paper using P after this held by controller 70 based on the position of the front end of the throughput direction of the paper using P detected by the 1st sensor 74.

The later process of the S104 of Fig. 7 is for detecting the paper using P that carries to recording unit 28 process relative to the diagonal of throughput direction.Before this series of processes of execution, controller 70 is as the work of the diagonal for eliminating paper using P in advance, and any one in (A) that carry out below and two shown in (B) kind of work.

(A) under the state of rotation that stopped supply driven roller 34, by driving feed drive roller 37 to rotate to contrary direction during conveying with paper using P, thus the front end of the throughput direction of paper using P is turned back to than till position by the upstream, this position from being transferred position that driven roller 37 and conveying driven voller 38 clamp.Thus, the front end being transferred the paper using P of driven roller 37 and the clamping of conveying driven voller 38 is discharged by throughput direction upstream side (left side of Fig. 1), and paper using P bends.If paper using P bends like this, then the front end of the throughput direction of paper using P is encountered the feed drive roller 37 in reversely rotating or stopping and between conveying driven voller 38, is achieved the elimination of paper using P relative to the diagonal of throughput direction by this collision.

(B) be set to: drive supply driven roller 34 rotate to the positive direction as direction during conveying paper using P and drive feed drive roller 37 rotate to the direction contrary with during conveying paper using P or make it stopped the state of rotary actuation.Thus, the front end of the throughput direction of paper using P, is encountered between above-mentioned such feed drive roller 37 of reversely rotating or stop the rotation and conveying driven voller 38, is achieved the elimination of the diagonal relative to throughput direction of paper using P by this collision.In addition, should the work of (B), preferably, adopt when being the thicker and hard paper using such as the paper using of 3D printing at paper using P.

After the work carrying out the above-mentioned diagonal for eliminating paper using P in advance, paper using P is carried to recording unit 28 by delivery section 27 by controller 70.And about with or without the diagonal not eliminating most paper using P in above-mentioned work, the process later by the S104 of Fig. 7 judges.In this series of process, first, as the process of S104, the front end being detected the throughput direction of paper using P by the 2nd sensor 75 is judged whether.If be affirmative determination here, then as the process of S105, stop carrying paper using P by delivery section 27, afterwards as the process of S106, make balladeur train 18 move to the 2nd position P2.

The process of this S106 is carried out as follows by controller 70.That is, controller 70 makes balladeur train 18 mobile to the side (the arrow X1 direction of Fig. 4 or arrow X2 direction) of scanning direction.Now, when paper using P not detected by the 2nd sensor 75, i.e. when making balladeur train 18 move to arrow X1 direction in the example of Fig. 4, the movement of the balladeur train 18 of the amount of regulation displacement x is carried out.Thus, balladeur train 18 arrives the 2nd position P2 as shown in Figure 5.

On the other hand, when the side making the balladeur train 18 of Fig. 4 to scanning direction as described above moves, when being continued paper using P to be detected by the 2nd sensor 75, make the moving direction of this balladeur train 18 reverse.In addition, in the example in fig. 4 when making balladeur train 18 move to arrow X2 direction namely when making balladeur train 18 move to the direction contrary with the 2nd position P2, continued paper using P to be detected by the 2nd sensor 75.In this situation, controller 70 makes the moving direction of balladeur train 18 oppositely (being reversed arrow X1 direction from arrow X2 direction in the example in fig. 4), carries out the movement of the balladeur train 18 of the amount of regulation displacement x afterwards.Thus, balladeur train 18 arrives the 2nd position P2 as shown in Figure 5.

Under the state that the process by above-mentioned S106 (Fig. 7) makes balladeur train 18 be moved to the 2nd position P2, as the process of S107, again start the conveying of the paper using P undertaken by delivery section 27.Then, as the process of S108, judge whether the 2nd sensor 75 detects the front end of the throughput direction of paper using P.If be certainly judge, then as the process of S109, obtain the diagonal angle θ of paper using P relative to the throughput direction of paper using P here.Specifically, following formula " θ=arctan (y/x) " is adopted to calculate above-mentioned diagonal angle θ based on fed distance y and regulation displacement x.

Next, as the process of S110, judge whether diagonal angle θ is more than decision content.In addition, as decision content used, can consider to adopt the high limit of tolerance value (such as 0.5 °) of the diagonal angle θ that correctly can implement 3D printing here.And, when diagonal angle θ equals "+0.5 ° " or forward is larger, in S110, make affirmative determination.In addition, when diagonal angle θ equals "-0.5 ° " or negative sense is larger, in S110, also affirmative determination is made.

When making affirmative determination in S110, be judged as that paper using P there occurs diagonal, as the process of S111, not recording unit 28 carry out for paper using P printing ground, this paper using P is carried by delivery section 27 and is discharged to stacker 23.On the other hand, when making negative evaluation in S110, as the process of S112, start the printing carrying out for paper using P in recording unit 28.

In addition, when paper using P hardly diagonal (when diagonal angle θ is 0 ° substantially), even if make balladeur train 18 move to either direction in arrow X1 direction and arrow X2 direction in the process of S106, it is constant that the 2nd sensor 75 is still likely in the state detected.In this case, be judged as that paper using P is without diagonal, start the printing for paper using P.

Next, relate to regard to printing equipment 11 below [A] ~ [C] item be separately described in detail.The 2nd sensor 75 in [A] balladeur train 18 relative to record head 20 nozzle, the storage of amount of bias in a scanning direction.Accuracy of detection during [B] the 2nd sensor 75 deterioration is guaranteed.[C] corresponding to diagonal angle θ, black liquid improves the attachment precision of paper using P.

The controller 70 of [A] printing equipment 11, in order to carry out the printing for paper using P, making balladeur train 18 suitably move along scanning direction and ink droplet is ejected from the nozzle of record head 20.Now spray timing ink droplet from nozzle, with the end of the scanning direction of the paper using P detected by the 2nd sensor 75 for benchmark and determining.Controller 70 stores the amount of bias Δ X in a scanning direction of the 2nd sensor 75 relative to the nozzle of record head 20, with the end of the scanning direction of paper using P for benchmark and determine to spray timing ink droplet from nozzle to paper using P based on above-mentioned amount of bias Δ X.

Fig. 8 and Fig. 9 is for illustration of above-mentioned amount of bias Δ X and the schematic drawing to the relation of the injection beginning position of the ink droplet of above-mentioned paper using P.

When suppose the above-mentioned amount of bias Δ X that stores of controller 70 result from printing equipment 11 foozle etc. and deviate from actual value, from nozzle needle sprays ink droplet to paper using P, timing may depart from correct timing.In addition, when the paper using P of 3D printing, require: after the end E being detected the scanning direction of paper using P by the 2nd sensor 75, consider above-mentioned amount of bias Δ X with this end E for benchmark, make ink droplet to start with being attached to the center M of the lens on paper using P to spray ink droplet from nozzle.But, if the amount of bias Δ X that controller 70 stores deviate from actual value, be then difficult to make ink droplet start with being attached to the center M of the lens on paper using P to spray ink droplet from nozzle.

In order to tackle this situation, in the manufacture process of printing equipment 11, preferably, by following steps A 1 ~ A3, the amount of bias Δ X of realistic value is stored in controller 70.

As shown in Figure 10, in steps A 1, carried out the printing of stairs-like image by low resolution by the paper using P (such as adjusting special glossy paper) of printing equipment 11 to adjustment.Specifically, controller 70 makes the end E of balladeur train 18 along scanning direction to paper using P move, and ink droplet is sprayed in the optional position " 0 " of front at end E from the nozzle of record head 20, sprayed the printing carrying out the stairs-like image shown in figure by ink droplet afterwards.The low resolution adopting such as 1/360dPi such can be considered as resolution ratio now.And, based on the detection of the end E undertaken by the 2nd sensor 75, which section is the stage portion closest to end E held in the stage portion (illustrating in this embodiment till the 1st ~ 3rd section) of stairs-like image be, and the distance obtained between this stage portion and position reset in a scanning direction, this distance is set as the temporary transient setting value of amount of bias Δ X.

In steps A 2, printing equipment 11 is utilized to adopt the amount of bias Δ X (temporary transient setting value) of setting in steps A 1 to carry out the printing of the stairs-like image same with steps A 1 by high-resolution (such as 1/1440dPi) for paper using P.It is that controller 70 to be held in the multiple stage portion in the stairs-like image printed out closest to the stage portion of end E for which section, and the distance obtained between this stage portion and position reset in a scanning direction, this distance is set as the new temporarily setting value of amount of bias Δ X.

In steps A 3, repeatedly carry out steps A 1 and steps A 2 at three different positions of paper using P, and add up to the temporary transient setting value of acquisition 4 amount of bias Δ X.And, the obtained mean value that is averaged to these four temporary transient setting values is set as formal amount of bias Δ X.Controller 70 stores the formal amount of bias Δ X of setting like this, and carries out later printing (injection of ink droplet) based on the amount of bias Δ X of this storage.In addition, the position of the paper using P of steps A 1 and steps A 2 is carried out as the temporary transient setting value in order to obtain amount of bias Δ X, preferably, the right part of throughput direction upstream in corner, i.e. the paper using P of paper using P and the right part in left part and throughput direction downstream and left part is used.

Below the formal amount of bias Δ X set like that is pre-stored within controller 70, and the amount of bias Δ X based on this storage prints, even if thus when 3D printing etc. requires high-precision printing like that, also can meet this requirement.In addition, by carrying out steps A 1 before carrying out steps A 2, compared with not carrying out the situation of steps A 1, steps A 2 high efficiency can be made.

[B], as the 2nd sensor 75, can consider to adopt: carry out to paper using P luminescence, carry out on the other hand the light of the reverberation from paper using P, carry out the sensor of the detection of paper using P based on light income now.But in the 2nd such sensor 75, because deterioration causes luminous quantity to reduce, the reduction of luminous quantity causes reducing from the light income of the reverberation of paper using P, so, cause lack accuracy when detecting the end of paper using P by the 2nd sensor 75.Therefore, in the 3D printing requiring to print the high accuracy of paper using P etc., detect the low of the accuracy of detection of the end of paper using P with the 2nd sensor 75, possibly cannot meet the requirement of the printing precision for paper using P.

In order to tackle this situation, preferably, correspondingly adjusting luminous quantity by the deterioration of step B1 below ~ B4 and the 2nd sensor 75, suppressing the 2nd sensor 75 to detect the low of the accuracy of detection of the end of paper using P thus.

In step bl is determined., under the state that controller 70 is in the 2nd position P2 after the process performing the diagonal for detecting paper using P and at balladeur train 18, by being carried to conveyance direction downstream side by paper using P, the 2nd sensor 75 is positioned on paper using P.

In step B2, controller 70, be arranged in the 2nd sensor 75 on paper using P, making the increase with light income and the detection voltage that lowers adjusts luminous quantity with becoming predetermined value (such as 0.4v), prestore the luminous quantity detected when voltage becomes predetermined value.

In step B3, controller 70 makes balladeur train 18 move to the 1st position P1 from the 2nd position P2, and adjusts the luminous quantity of the 2nd sensor 75 in this position in the same manner as step B2.And the detection voltage prestoring the 2nd sensor 75 becomes luminous quantity during predetermined value.

In step B4, controller 70 is set in the mean value of the luminous quantity stored respectively in step B2 and step B4 as the new luminous quantity in the 2nd sensor 75.Thus, the 2nd sensor 75 that utilizes carried out afterwards detects in the detection of the end of paper using P, carries out the luminescence to paper using P by the luminous quantity of new settings as described above.

In addition, about the adjustment of the luminous quantity to the 2nd sensor 75 undertaken by above-mentioned steps B1 ~ B4, also can only wait and carry out for during printing under the high accuracy of paper using P carrying out 3D printing.In this situation, when paper using P is the paper using without the need to high accuracy printing of general printing use and so on, does not carry out the adjustment of the luminous quantity of the 2nd sensor 75 undertaken by step B1 ~ B4, carry out luminescence by the luminous quantity of regulation.

[C], when the diagonal angle θ of paper using P is less than decision content and the diagonal of paper using P do not detected, although start the printing for paper using P, undeniable, ink droplet reduces by the amount of diagonal angle θ relative to the attachment precision of paper using P.And when carrying out the printing for the paper using P of 3D printing, the attenuating of the attachment precision of such ink droplet can cause negative effect to printing.Therefore, when carrying out the printing of paper using P for 3D printing and large at diagonal angle θ ratio " 0 " time, preferably, achieve on the basis of good print for the lifting of the attachment precision of paper using P achieving ink droplet, discuss certain countermeasure.As such countermeasure, can consider: make the ink droplet by spraying from the nozzle of record head 20 and the image that prints out at paper using P by the amount of diagonal angle θ, in the same manner as paper using P obliquely, stagger and spray the injection timing of ink droplet from nozzle.

Here, as shown in Figure 10, at record head 20, arranged nozzle by the throughput direction (above-below direction in figure) along paper using P and be formed with nozzle rows, such nozzle rows is formed multiple along the scanning direction of balladeur train 18 with arranging.In addition, in 3D printing, as paper using P, as shown in Figure 9, the lens being such as bonded to black liquid absorbed layer in the bottom surface of biconvex lens is used.Lens (such as cylindrical lens) on paper using P are as shown in Figure 9 under the upper state extended of throughput direction (above-below direction of Fig. 9), namely under the state extended side by side with the nozzle rows shown in Figure 10, carry out the conveying of paper using P.When supposing that diagonal angle θ is " 0 ", by spraying ink droplet from each nozzle in nozzle rows simultaneously, ink droplet can be made to be attached to the center M of the lens on paper using P, image can be made to paper using P without printing obliquely.On the other hand, when diagonal angle θ ratio " 0 " is large, by the injection timing and diagonal angle θ that spray ink droplet from the nozzle in a nozzle rows are correspondingly staggered gradually by each of each nozzle, the center M of the lens on the paper using P that ink droplet can be made to be attached to tilted by the amount of diagonal angle θ, can tilt image by the amount of diagonal angle θ to paper using P and print.

In addition, will spray the injection timing of ink droplet and diagonal angle θ correspondingly staggers gradually by each of each nozzle from the nozzle in a nozzle rows, the delay setting etc. by each ink droplet injection timing of each nozzle corresponding to diagonal angle θ realizes.In addition, the injection timing and diagonal angle θ that spray ink droplet from the nozzle in a nozzle rows are correspondingly staggered gradually by each of each nozzle, also can realize as follows.That is, namely the image based on the print job data sent from such as host apparatus 71 is used for the source images carried out for the printing of paper using P to tilt by the amount of diagonal angle θ.In this situation, based on the source images that the amount by diagonal angle θ has tilted, spray ink droplet from each nozzle of the nozzle rows of record head 20, so the injection timing that each nozzle from a nozzle rows can be sprayed ink droplet staggers as described above.

According to the present embodiment detailed above, the effect shown in below can obtaining.

(1) when the diagonal of paper using P relative to throughput direction of carrying to recording unit 28 not detected, the time till the printing played from the delivery section 27 of the detection for this diagonal and the work of balladeur train 18 for paper using P starts can be shortened.

(2) in order to detect paper using P relative to the diagonal of throughput direction, balladeur train 18 is moved to the 2nd position P2 from the 1st position P1 along scanning direction time, the balladeur train 18 being in the 1st position P1 may be made to move to the direction contrary with the 2nd position P2 at first.When paper using P is relative to throughput direction diagonal, balladeur train 18 start to the 2nd position P2 rightabout mobile time, continued paper using P to be detected by the 2nd sensor 75.When being continued paper using P to be detected by the 2nd sensor 75 like this, the moving direction of balladeur train 18 is made oppositely to make this balladeur train 18 towards the 2nd position P2.Thus, even if make above-mentioned balladeur train 18 move from the 1st position P1 to the direction contrary with the 2nd position P2, also can by the diagonal oppositely detecting paper using P of the moving direction of balladeur train 18 afterwards.Now, if make oppositely towards the 2nd position P2, then will to suppress the meaningless movement of the balladeur train 18 when moving from the 1st position P1 to the 2nd position P2 as far as possible immediately to the moving direction of the balladeur train 18 with the 2nd position P2 rightabout movement.

(3) the diagonal angle θ of paper using P relative to throughput direction is obtained based on fed distance y and regulation displacement x.Based on this diagonal angle θ this situation more than decision content, can be judged as that paper using P there occurs diagonal.In other words, then based on diagonal angle θ this situation more than decision content, detect that paper using P is relative to throughput direction diagonal.In addition, above-mentioned decision content is set to, and correctly can implement the high limit of tolerance value of the diagonal angle θ of 3D printing.And, above-mentioned detected the diagonal of paper using P like that time, make this paper using P to throughput direction discharge delivery section 27 is worked.Therefore, the diagonal of paper using P attend the meeting greatly the degree of obstacle causes to the 3D printing carried out for this paper using P time, this paper using P can be discharged to throughput direction.Therefore, it is possible to avoid the paper using P for diagonal to carry out 3D printing, consume the situation of paper using P in vain thus.

(4) for determining that the regulation displacement x of the 2nd position P2 is set to, shorter than the distance from the end (being the end in direction of arrow X1 in this embodiment) on the scanning direction in the 1st position P1 to paper using P and be that balladeur train 18 is as far as possible close to the value of above-mentioned end.About regulation displacement x, obtaining on the basis of diagonal angle θ accurately based on this regulation displacement x etc., preferably, as much as possible greatly.If set regulation displacement x as described above, then this regulation displacement x can be made large as much as possible, diagonal angle θ can be obtained accurately.In addition, if be set to the formation correspondingly determining the 2nd position P2 (specifying displacement x) with the paper size in printing condition information, then without the need to carry out for determine the 2nd position P2 in order to paper size is detected, make balladeur train 18 (the 2nd sensor 75) movement in a scanning direction.

(the 2nd embodiment)

Next, reference Figure 11 ~ Figure 19 is while be described with regard to the 2nd embodiment.Present embodiment is following example: when the surveyed area of the 2nd sensor 75 does not exist paper using P, even if the part of the brace table 39 of the example of support portion shone as the light irradiated from the 2nd sensor 75 be the light income of the 2nd sensor 75 because of the illumination male and fomale(M&F) shape different to position, also can guarantee that the accuracy of detection of diagonal is high.

As shown in figure 11, be arranged at the brace table 39 of printing equipment 11, mobile route (scanning direction) along balladeur train 18 extends by long size shape, and supports the preset range comprising the paper using P of the part corresponding with the printing zone PA being carried out the injection of liquid by record head 20.Brace table 39 has: the upstream side being positioned at the upstream side of throughput direction supports face 81; The stage casing support face 82 that face 81 is positioned at the downstream of throughput direction is supported relative to upstream side; Face 83 is supported with the downstreams being positioned at the downstream of throughput direction relative to stage casing support face 82.Support face 82 in stage casing and be configured with printing zone PA.

As shown in figure 11, upstream side support face 81 be formed with separating predetermined space in a scanning direction multiple on the upside of vertical (in front of the paper of Figure 11 side) outstanding and along throughput direction extension the 1st rib 84.In addition, stage casing support face 82 be formed with separating certain intervals in a scanning direction multiple on the upside of vertical outstanding and along throughput direction extension the 2nd rib 85.Further, downstream support face 83 be formed with separating certain intervals in a scanning direction multiple on the upside of vertical outstanding and along throughput direction extension the 3rd rib 86.Be transferred along throughput direction under the state that paper using P (with reference to Fig. 1) is supported by the 1st ~ 3rd rib 84 ~ 86 overleaf.

In addition, as shown in figure 11, support face 82 in stage casing to be provided with and to comprise printing zone PA and the black liquid absorbing component 87 of four longer in a scanning direction side plate shapes.Ink liquid absorbing component 87 has: the function etc. being such as absorbed in be ejected into paper using P when non-flanged is printed outside with overflowing and the black liquid adhered to.Paper using P is supported with the state left upward from the surface of black liquid absorbing component 87 by multiple 2nd rib 85.

As shown in figure 11, the part except the 1st rib 84 of upstream side support face 81 becomes the recess 81a with the bottom surface lower than the end face (upper surface) of the 1st rib 84.The bottom surface of recess 81a becomes male and fomale(M&F) 81b (with reference to Figure 12) as described later.On the other hand, the 2nd sensor 75 is arranged at balladeur train 18 to be configured at the state supporting the corresponding position of face 81 with upstream side in the conveying direction.Therefore, when carrying out the work of diagonal detecting paper using, the 2nd sensor 75 under paper using is not present in the state that upstream side supports on face 81, to the reverberation light supporting face 81 from upstream side.In addition, linear encoder 72 has: the marking plate 72a with many gaps of the opening at a certain distance along scanning direction; With with light accepting part to from light-projecting portion outgoing and the light that have passed gap carries out the sensor 72b of light.

As shown in Figure 12 (a), (b), support the bottom surface of the recess 81a in face 81 at upstream side, be arranged with multiple protuberances 88 (rib) that aspect ratio the 1st rib 84 is low in a scanning direction at a certain distance.As shown in Figure 12 (b), the side-looking observed from throughput direction of protuberance 88 be trapezoidal shape, and there is the highest end face 88a (upper surface) and in the both sides, scanning direction of end face 88a by certain angle inclination extension and respective inclination towards different two inclined-planes 88b, 88c.And minimum bottom surface 88d is between protuberance 88.Like this, the bottom surface of recess 81a becomes male and fomale(M&F) 81b due to the existence of multiple protuberances 88 such shown in Figure 12 (a), (b).

Therefore, be irradiated to the light easily diffuse reflection because of male and fomale(M&F) 81b of recess 81a from the 2nd sensor 75, the light quantity to the 2nd sensor 75 incidence is reduced relatively.In contrast, the light reflectivity of paper using P is compared with recess 81a, relatively high.Therefore, for the 2nd sensor 75, recess 81a becomes dark portion region, and paper using P becomes highlights region.Therefore, time in the surveyed area (luminous point) that the front end of paper using P arrives the 2nd sensor 75, the light volume reflection returning the 2nd sensor 75 in the both sides on border that paper using P and upstream side support face 81 easily produces difference, can with the front end of the throughput direction of higher accuracy detection paper using P.

In addition, the end face 84a of the 1st rib 84 is polished because paper using P slides, gradually becomes mirror-like.Therefore, the light reflectivity of end face 84a changes till becoming mirror-like to uplifted side gradually.Luminous point SP during the front end of detection paper using P is shone the 1st this situation of rib 84 that light reflectivity changes like this, from the angle obtaining correct conveying capacity, not preferred like that.Therefore, in the present embodiment, the luminous point SP of the 2nd sensor 75 is shone aspect ratio the 1st rib 84 low first do not slide with paper using P, the relative less recess 81a of change of light reflectivity.Therefore, by the 2nd position P2 (being also denoted as below " P2o ") of allocation position i.e. the 1st position P1 of the 2nd sensor 75 when carrying out the work of diagonal detecting paper using P and the 2nd position P2 (being also denoted as below " P2h ") of initial position side and initial position opposition side, be set in the region of recess 81a.

According to centered by which face of the luminous point being irradiated to recess 81a from the 2nd sensor 75 when detecting the diagonal of paper using P by 3 of protuberance 88 face 88a ~ 88c and bottom surface 88d irradiate, the light income of the 2nd sensor 75 can be variant.Namely, according to irradiating centered by which face of the luminous point from the 2nd sensor 75 in 4 face 88a ~ 88d, the output valve of the 2nd sensor 75 can be variant.In addition, the 2nd sensor 75 of present embodiment is configured to, shine at luminous point the dark portion regions such as recess 81a and light income few time, its output valve becomes large, and when luminous point shines the highlights region of paper using P etc., light income is many, its output valve diminishes.Certainly, the 2nd sensor 75 also can be the light income formation that output valve is higher more at most.

As shown in figure 13, in this example, if the width of end face 88a is set to L1, inclined-plane 88b is set to L2 to the projection width of scanning direction, inclined-plane 88c is set to L3 to the projection width of scanning direction and the width of bottom surface 88d is set to L4, then as an example, become L1=L2=L3=L4.Such as, the width L1 of end face 88a is value in the scope of 0.1 ~ 2mm (be 0.5mm as an example).In addition, the spot diameter of the 2nd sensor 75 longer than the width L1 of end face 88a, be such as 0.5 ~ 5mm scope in value (be 2mm as an example).And then, the nozzle forming surface of nozzle opening and the distance of the supporting surface end face of rib 85 (in this example for) loading paper using P in brace table 39 in record head 20, change according to the kind of paper using P, when the paper using P as diagonal detected object of present embodiment, be set as value in the scope of 1 ~ 3mm (be 2mm as an example).

Therefore, when making the center of luminous point consistent with the widthwise central of end face 88a, in luminous point, comprise end face 88a and inclined-plane 88b, 88c.Certainly, the relation of the width L1 of spot diameter D and end face also can be D≤L1.In addition, each width L1 ~ L4 on the scanning direction of each 88a ~ 88d both can be all different, also can a part different and another part is identical.

As shown in Figure 14 (a), (b), in the example of D=4L1, in the luminous point SP of the 2nd sensor 75, comprise the whole of multiple 88a ~ 88d of protuberance 88.Such as shown in Figure 14 (a), when luminous point SP be centrally located at end face 88a, in luminous point SP, comprise end face 88a, its both sides adjacent inclined-plane 88b, 88c and a little bottom surface 88d.In addition, such as, shown in Figure 14 (b), when luminous point SP be centrally located at bottom surface 88d, in luminous point SP, comprise bottom surface 88d, its both sides adjacent inclined-plane 88b, 88c and a little end face 88a.

In the curve map that sensor in fig. 13 exports, the center of the luminous point SP of positional representation the 2nd sensor 75 of stain.As shown in figure 13, when luminous point SP be centrally located at the end face 88a of protuberance 88 (suitable with Figure 14 (a)), the light volume reflection of the 2nd sensor 75 light tails off relatively, and sensor output value becomes large relatively.In contrast, when luminous point SP be centrally located at bottom surface 88d (suitable with Figure 14 (b)), the light volume reflection of the 2nd sensor 75 light becomes many relatively, and sensor output value diminishes relatively.This is because: the light that such as reason inclined-plane 88b reflects is reflected further by opposed inclined-plane 88c and is incident in the light of the 2nd sensor 75, makes the light income of the 2nd sensor 75 relatively become many.In addition, luminous point SP be centrally located at inclined-plane 88c (or 88b) when, the light volume reflection of the 2nd sensor 75 light, become luminous point be centrally located at end face 88a when with the amount of centre when being positioned at bottom surface 88d, sensor output value also becomes the value of the centre of both of these case.

Because the irradiation position of the luminous point SP of the 2nd sensor 75 moves on the male and fomale(M&F) 81b of recess 81a along with the movement on the scanning direction of balladeur train 18 in this wise, sensor is output into as shown in figure 13 corresponding to the shape of protuberance 88 and periodically variable waveform signal.And be in which position in which face in four face 88a ~ 88d according to the center of the luminous point SP of the 2nd sensor 75, sensor output can change.

Such as at the 1st position P1 and the 2nd position P2o (or P2h), when the face residing for center of the luminous point in four face 88a ~ 88d is different, the output valve of the 2nd sensor 75 dissimilates.In this situation, till reaching until sensor output value the threshold value being judged to be paper, carry the conveying capacity required for paper using P, can deviation be produced.

Figure 16 represents: from the 2nd sensor 75 pairs of upstream sides support face 81 irradiate the state of light, to be transferred and the 2nd sensor 75 detects in the process of the front end of paper using P at paper using P, paper using P enters the curve map of the conveying capacity (paper feeding amount) in luminous point SP and the relation of the output of the 2nd sensor 75.In the plot, as an example, by as Figure 14 (a), shown in (b), luminous point SP of the 2nd sensor 75 only shines the male and fomale(M&F) 81b of recess 81a and is cut in luminous point SP outside the front end of paper using P time position, be set to the base position of conveying capacity " 0 ".In the curve map of Figure 16, center with regard to luminous point SP lays respectively at the situation of the end face 88a (Figure 14 (a)) of protuberance 88, inclined-plane 88b, 88c, bottom surface 88d (Figure 14 (b)), illustrates that paper using P enters from base position the relation that conveying capacity in luminous point SP and sensor export.

In the curve map of Figure 16, solid line illustrate represent luminous point be centrally located at end face 88a when conveying capacity and graph line (graph line) LT of relation that exports of sensor, single dotted broken line illustrate luminous point be centrally located at inclined-plane 88b, 88c when same graph line LS, double dot dash line illustrate luminous point be centrally located at bottom surface 88d when same graph line LB.In addition, the thick dashed line in the curve map of Figure 16 is the threshold value Th of the 2nd sensor 75 when paper using P being detected.If the output valve inputted from the 2nd sensor 75 reaches this threshold value Th, then controller 70 is judged to detect paper using P.

As shown in figure 16, the conveying capacity of paper using P required till the sensor output value at base position (conveying capacity " 0 ") place reaches threshold value Th, by luminous point SP center residing for position be end face 88a (solid line), inclined-plane 88b, 88c (single dotted broken line), bottom surface 88d (double dot dash line) order and become many.This is due to following reason.

As shown in Figure 14 (a), when the center of luminous point SP is in the end face 88a of protuberance 88, relatively dark in luminous point SP, so sensor output value a becomes large relatively as shown in figure 16.In addition, as shown in Figure 14 (b), when the center of luminous point SP is in the bottom surface 88d of protuberance 88, relatively bright in luminous point SP, so sensor output value c diminishes relatively as shown in figure 16.And then when being in inclined-plane 88b, 88c of protuberance 88 at the center of luminous point SP, sensor output value b is the value between output valve a and output valve c as shown in figure 16.

Figure 15 (a) illustrates that the situation lower sensor that the center of luminous point SP is in the end face 88a of protuberance 88 exports the situation reached in threshold value Th time point SP, and Figure 15 (b) illustrates that the situation lower sensor that the center of luminous point SP is in the bottom surface 88d of protuberance 88 exports the situation reached in threshold value Th time point SP.As shown in Figure 14 (a), when luminous point SP be centrally located at end face 88a, in luminous point SP relatively dark (low light volume reflection), so as shown in Figure 15 (a), until sensor output value reaches threshold value Th, the paper using P that light reflectivity is high needs the ratio of occupying of occupying in luminous point SP relatively to become large.Therefore, until the conveying capacity that sensor output value reaches the required paper using P of threshold value Th becomes large relatively.

On the other hand, as shown in Figure 14 (b), when luminous point be centrally located at bottom surface 88d, relatively bright in luminous point SP (high light reflectivity amount), so as shown in Figure 15 (b), till sensor output value reaches threshold value Th, paper using P needs the ratio of occupying of occupying in luminous point SP relatively to diminish.Therefore, until the conveying capacity that sensor output value reaches the required paper using P of threshold value Th diminishes relatively.

Namely, as shown in figure 17, when luminous point be centrally located at end face 88a and sensor export get relatively high value " a " (suitable with Figure 14 (a)), until sensor exports reach threshold value Th, need to increase relatively many light income Δ S1, therefore, the conveying capacity y1 of required paper using P becomes many relatively.Relative to this, as shown in figure 17, when luminous point be centrally located at bottom surface 88d and sensor export get relatively low value " c " (suitable with Figure 14 (b)), as long as until sensor exports reach the relatively less light income Δ S3 of threshold value Th increase, therefore, the conveying capacity y3 (< y1) of required paper using P is relatively little.And then, as shown in figure 17, when luminous point SP be centrally located at inclined-plane 88c (or 88c) and sensor export get median " b ", until sensor output value b reaches threshold value Th, need to increase the light income Δ S2 between Δ S1 and Δ S3, therefore, the conveying capacity y2 (wherein, y3 < y2 < y1) of required paper using P also becomes median.

In addition, when the 2nd sensor 75 has been configured to the 1st position P1 or the 2nd position P2, because the assembling deviation of brace table 39 or the 2nd sensor 75 are relative to the deviation etc. of the assembling position of balladeur train 18, the center of time point SP is had to depart from slightly from the widthwise central of end face 88a in a scanning direction.As shown in Figure 15 (a), paper using P in luminous point SP when detecting the front end of paper using P occupy ratio relatively large, even if the position of the male and fomale(M&F) 81b in luminous point SP is departed from a scanning direction, because the male and fomale(M&F) 81b in luminous point SP to occupy ratio relatively little, so to depart from the caused impact exported sensor relatively little due to this.

Relative to this, as shown in Figure 15 (b), paper using P in luminous point SP when detecting the front end of paper using P occupy ratio relatively little, when the position of the male and fomale(M&F) 81b in luminous point SP is departed from a scanning direction, because the male and fomale(M&F) 81b in luminous point SP to occupy ratio relatively many, so caused become relatively large to the impact that sensor exports because this departs from.

Because such reason, in the present embodiment, the 2nd position P2h of the 1st position P1, initial position side and the 2nd position P2o of initial position opposition side is set to: the center configuration of luminous point SP is in the position of the end face 88a of protuberance 88.Especially in this example, the 1st position P1 and two the 2nd position P2h, P2o is set to the widthwise central of end face 88a.These each position P1, P2h, P2o, the count value that the counted number of pulses as the linear encoder 72 of the position with assurance balladeur train 18 is suitable is stored in the not shown nonvolatile memory in controller 70.

In addition, controller 70 is by abutting the reference position on the scanning direction obtaining balladeur train 18.Specifically, controller 70, makes balladeur train 18 move till the terminal location encountering initial position side by making carriage motor 40 drive, thus abuts, the counter of the position reset sledge position counting when encountering terminal location.Like this by abutting the reference position (such as count value " 0 ") obtaining balladeur train 18.Then, controller 70 reads each desired location of the 1st position P1 predetermined male and fomale(M&F) 81b and the 2nd position P2 (P2h, P2o) from nonvolatile memory.Balladeur train 18 is moved in a scanning direction, if the counter reaching the sledge position counting be reset in reference position is set to the 1st position P1 or the 2nd position P2 of target now, then makes balladeur train 18 stop.Thus, balladeur train 18 is comparatively positioned the 1st position P1 or the 2nd position P2 in a scanning direction.

In addition, as additive method, controller 70, under the state that paper using P is not present on brace table 39, balladeur train 18 moved and detect the identical position (such as end face 88a) of the shape of male and fomale(M&F) 81b by the 2nd sensor 75, based on this position detected obtain the counter suitable with the widthwise central of end face 88a count value and as the 1st position P1 and the 2nd position P2.Such as, based on the output valve of the 2nd sensor 75 shown in Figure 13, obtain the position (such as the widthwise central of end face 88a) that the shape of the male and fomale(M&F) 81b preset for each protuberance 88 corresponding respectively with the 2nd position P2 with the 1st position P1 is identical, and the position this obtained is set as the 1st position P1 and the 2nd position P2.Such as also can initialization when power supply is connected time or printing number when reaching the scheduled time apart from elapsed time during previous setting process or from previous setting process when reaching predetermined number, carry out the 1st such position P1 and the setting process of the 2nd position P2.Then, balladeur train 18 is made to move and the 2nd sensor 75 is configured to the 1st position P1 and the 2nd position P2 of this setting.

Next, the effect of above-mentioned such printing equipment 11 formed is described.

As shown in figure 18, when the 2nd sensor 75 is configured at the 1st position P1, the widthwise central being centrally located at end face 88a of this luminous point SP.In addition, when the 2nd sensor 75 is configured at the 2nd position P2 (P2h or P2o), when the 2nd position P2 is any position in the position P2h of initial position side and the position P2o of initial position opposition side, the center of luminous point SP is all positioned at the widthwise central of end face 88a.Its result, as shown in figure 18, when each position P1, P2 detect paper using P, in which face being centrally located at protuberance 88 according to luminous point SP by arbitrary waveform in the sensor output waveform (waveform signal) of wave change, sensor exports the value of all getting near maximum.And, paper using P is carried until under sensor exports the state reaching threshold value Th in the front end in order to detect paper using P, at each position P1, P2, the ratio of occupying of the paper using P in luminous point SP all becomes the equal state shown in Figure 15 (a), so can obtain more correct conveying capacity.

In contrast, such as, when the 1st position P1 detects the front end of paper using P, shown in the occupation ratio such as Figure 15 (a) of the paper using P in luminous point SP, for relatively many.Then, paper using P is when ensuing 2nd position P2 detects its front end in conveying, shown in the occupation ratio of the paper using P in luminous point SP such as Figure 15 (b), be relatively less.In this situation, the amount that fed distance y therebetween can be corresponding in the difference of occupying ratio to the paper using in luminous point SP has deviation.But in this example, each position P1, P2 are set at the identical position of the shape of male and fomale(M&F) 81b, at each position P1, P2, the paper using P in luminous point SP to occupy ratio roughly the same, so, comparatively can obtain fed distance y therebetween.Therefore, it is possible to utilize this fed distance y and regulation displacement x and obtain diagonal angle θ more accurately.

In addition, due to the deviation etc. of the assembling position of the brace table 39 in printing equipment 11, sometimes depart from a scanning direction relative to the position in design relative to the origin position of balladeur train 18, male and fomale(M&F) 81b.In this situation, even if the 1st position P1 stored at nonvolatile memory and the 2nd position P2 (P2h and P2o) configures the 2nd sensor 75, the center of this luminous point SP also can be departed from from the widthwise central of the end face 88a of protuberance 88.But, as shown in figure 19,1st position P1 and two the 2nd position P2h, P2o, departs from towards by same distance with same from the widthwise central of the end face 88a of corresponding protuberance 88 to scanning direction respectively, so be offset to the roughly same position of the same face of protuberance 88 separately.Namely, each position P1, P2 are offset to the identical position of the shape of male and fomale(M&F) 81b.Therefore, the sensor when each position P1, P2 do not have paper using P exports and becomes identical.Therefore, at any position P1, P2, paper using P be transferred and sensor output value reaches threshold value Th and detect the front end of paper using P time, paper using in luminous point SP occupy ratio, all become roughly the same.Thereby, it is possible to comparatively obtain fed distance y therebetween.Its result, when each position P1, P2 depart from a scanning direction relative to the end face 88a of protuberance 88, also can obtain diagonal angle θ by utilizing this fed distance y accurately.

Paper using P in luminous point SP when position P1, P2 detect the front end of paper using P occupy that ratio is respectively Figure 15 (a), state shown in (b), the error of the diagonal angle θ obtained becomes larger.In contrast, in the present embodiment, the ratio of occupying of the paper using P in the luminous point SP when position P1, P2 detect the front end of paper using P all becomes the state shown in Figure 15 (a), thus can obtain diagonal angle θ with the error of such as about 1/4.

According to above in detail the 2nd such embodiment is described in detail, except the effect identical with the 1st embodiment, effect below can also be obtained.

(5) by the 1st position P1 and the 2nd position P2 being set as the same position of the same face formed in multiple the 88a ~ 88d of male and fomale(M&F) 81b, set it to the position that the shape of male and fomale(M&F) 81b is identical, so regardless of the front end detecting paper using P in which face of protuberance 88, the fed distance y that contained error is little can both be obtained.Thereby, it is possible to utilize this fed distance y and regulation displacement x to calculate diagonal angle θ accurately.

(6) even if make position P1, P2 of the 2nd sensor 75 deviate from position (such as the widthwise central of end face 88a) on the face presupposed of protuberance 88 due to the assembling position deviation etc. of brace table 39, this departs from by same towards becoming roughly same distance.Therefore, at each position P1, P2, the output valve of the 2nd sensor 75 before the conveying of paper using P starts is all roughly the same, and paper using P in luminous point SP when being detected the front end of paper using P by the 2nd sensor 75 to occupy ratio roughly the same, so can obtain more correct fed distance y.Thereby, it is possible to utilize this fed distance y, obtain more correct diagonal angle θ.

(7) control part 70a is benchmark and predetermined 1st position P1 and the 2nd position P2 by abutting the reference position that obtains balladeur train 18 and being configured at reference position, thus carries out balladeur train 18 relative to male and fomale(M&F) 81b relative positioning in a scanning direction.Therefore, when the 2nd sensor 75 is configured at the 1st position P1 and the 2nd position P2, at any time the 2nd sensor 75 can both be configured at the position that the shape of male and fomale(M&F) 81b is identical.

(8) as additive method, controller 70, under the state that paper using P is not present on brace table 39, balladeur train 18 moved and detected by the position that the shape of the 2nd sensor 75 couples of male and fomale(M&F) 81b is identical, set based on testing result, make the 1st position P1 and the 2nd position P2 become the identical position of the shape of male and fomale(M&F) 81b.And, make balladeur train 18 move the 1st position P1 and the 2nd position P2 the 2nd sensor 75 to be configured at this setting.When adopting this formation, though brace table 39 be assembled with deviation etc., also the 2nd sensor 75 can be configured at the shape of male and fomale(M&F) 81b the 1st identical position P1 and the 2nd position P2.

(9) the 1st position P1 and the 2nd position P2 is set as the position on the end face 88a of protuberance 88.Such as bottom surface 88d is minimum part on male and fomale(M&F) 81b, so black liquid or delay sometimes or flowing, under these circumstances, because the impact of black liquid, light reflectivity easily change.But according to the present embodiment, the 1st position P1 and the 2nd position P2 is set to the position on the end face 88a of protuberance 88, so light reflectivity ratio is easier to stablize, can reduce error detection.In addition, can make when carrying paper using P and the output valve of the 2nd sensor 75 reach threshold value Th and detect the front end of this paper using P, in luminous point SP paper using P to occupy ratio relatively large.Therefore, even if position P1, P2 depart from from the widthwise central of the end face 88a of protuberance 88, because the ratio of occupying of the male and fomale(M&F) 81b in luminous point SP when detecting the front end of paper using P diminishes relatively, so this impact departed from is difficult to manifest, correspondingly comparatively fed distance y can be obtained.Its result, can utilize more correct fed distance y comparatively to obtain diagonal angle θ.

(10) the 1st position P1 and the 2nd position P2 are set to reverberation in the multiple face of the shape of regulation male and fomale(M&F) 81b, that reflect the light irradiated from the 2nd sensor 75 by the position the minimum face of the light income of the 2nd sensor 75 light.Therefore, until the output of the 2nd sensor 75 exceedes threshold value Th, the paper using P conveying capacity entered in luminous point SP becomes many relatively, so, can make the paper using P in the luminous point SP of the 2nd sensor 75 to occupy ratio relatively large.Therefore, even if such as due to the assembling deviation etc. of brace table 39, be configured at the position deviation more or less on the male and fomale(M&F) 81b of the 2nd sensor 75 of the 1st position P1 and the 2nd position P2, the impact of this deviation also can be made relatively to reduce.Thus, depart from comparatively speaking by this position, the error detection of diagonal can be reduced.

(11) in a scanning direction, the spot diameter being irradiated to the light of male and fomale(M&F) 81b from the 2nd sensor 75 is set larger than the width of end face 88a.Sometimes, due to the attachment of such as paper scrap or ink mist etc., in the certain surface of the detected object on male and fomale(M&F) 81b, local produces the position of light reflectivity exception.Under these circumstances, the diameter of luminous point SP is larger than the width of end face 88a, and the ratio of occupying at this abnormal position therefore in luminous point SP diminishes, so, the error detection of diagonal can be reduced.

In addition, the respective embodiments described above also can such as change as follows.

As long as 1st position P1, the position can being detected the front end of the throughput direction of the paper using P carried to recording unit 28 by the 2nd sensor 75, is not necessarily the central authorities of the scanning direction of paper using P.

Printing equipment 11 may not be the middle position of scanning direction of paper using P of carrying to recording unit 28 and the size of paper using P has nothing to do and always certain structure.Such as, the printing equipment placed with also can being applied to the end (reference edge) encountered by above-mentioned paper using P on scanning direction.In this situation, the middle position to the scanning direction of the paper using P of recording unit 28 conveying changes because of the size of paper using P, but the change of its middle position can be coordinated in other words to be the change coordinating paper using P size, and it is next corresponding to change the 1st position P1.

About regulation displacement x, as long as short unlike the distance the end from the above-mentioned scanning direction in the 1st position P1 to paper using P, if in other words, as long as then the 2nd position P2 does not stretch out from the above-mentioned end of paper using P outside scanning direction, also can meet such condition and suitably change.

About the delivery section 27 of the diagonal for detecting paper using P and the work of balladeur train 18, need not paper using P be carried all to perform to recording unit 28 at every turn, also can perform according to the kind of paper using P and still not performing.Such as, paper using P be 3D printing with this kind of need the paper using of carrying out high-precision printing time, perform the delivery section 27 of diagonal and the work of balladeur train 18 for detecting this paper using P, on the other hand, paper using P be general printing with this kind of without the need to carry out high-precision printing paper using time, also can not perform above-mentioned work.In this situation, if only above-mentioned paper using P be need to carry out the paper using of high-precision printing and the diagonal of paper using P becomes problem for the printing for this paper using P time in other words, only when needs detect this diagonal, the work of delivery section 27 for this detection and balladeur train 18 can be performed.On the other hand, when the diagonal that paper using P is paper using and paper using P without the need to carrying out high-precision record does not become problem relative to the printing for this paper using P, if in other words, when the detection without the need to carrying out this diagonal, the work of delivery section 27 for this detection and balladeur train 18 can not be carried out.In addition, by the detection of the diagonal of paper using P can be performed necessarily, also can suppress: the execution detected with this unnecessary diagonal, the situation that the time spent to the beginning of the printing for paper using P is elongated.

When detecting the diagonal of paper using P, the practice from stacker 23 to downstream conveying but the diagonal removal work making delivery section 27 carry out for eliminating paper using P diagonal that this paper using P are discharged to also can be replaced.As diagonal removal work now, can consider to carry out any operative in above-mentioned (A) and (B) these two kinds work.

Specifically, when detecting the diagonal of the paper using P carried to recording unit 28, by driving supply driven roller 34 and feed drive roller 37 to rotate to the direction contrary with during conveying paper using P, returning paper using P and making the front end of the throughput direction of paper using P be positioned at the position leaning on the upstream of throughput direction than feed drive roller 37 and conveying driven voller 38.In this condition, by carrying out any operative in these (A) and (B) these two kinds of diagonal removal work, the elimination of the diagonal of paper using P is again achieved.And, when practically eliminating diagonal in diagonal check processing once again (when making affirmative determination in S111), the printing this paper using P carried out in recording unit 28 can be started subsequently.Therefore, it is possible to save once be discharged to stacker 23 as the paper using P by diagonal situation, the paper using P of this discharge reapposed man-hour of feed cassette 16.

In addition, at above-mentioned embodiment like that, when this paper using P being discharged to conveyance direction downstream side (stacker 23 side) when detecting the diagonal of paper using P, even the structure that printing equipment cannot drive supply driven roller 34 to rotate round about also can be applied.

In the 2nd embodiment, as long as the 1st position P1 and the 2nd position P2 is set to the position of the same shape of male and fomale(M&F) 81b.Such as, the 1st position P1 and the 2nd position P2 both can be set as the position on inclined-plane 88b, also all can be set as the position on inclined-plane 88c.In addition, the 1st position P1 and the 2nd position P2 also can be set as the position on the 88d of bottom surface.In addition, when the 1st position P1 and the 2nd position P2 is set as the position on inclined-plane 88b, 88c, preferably, unified for tilting towards identical inclined-plane, but also can be set as towards each position on different inclined-plane 88b, 88c.

In the 2nd embodiment, protuberance also can be the 1st rib 84.Also the 1st position P1 and the 2nd position P2 can be set as the position that the shape of the 1st rib 84 is identical.In this situation, the bottom surface of recess 81a may not be male and fomale(M&F).

Object and the medium of the record of printing equipment are not limited to paper using, as long as can carry out the sheet medium of printing (record) by the recording unit of printing equipment, are what can.Also can be such as the complex film (stacked film), fabric, non-woven fabrics, metal forming, metal film, potsherd etc. of the complex film of resinous film, paper and resin, resin and metal.

In addition, the formation of each embodiment in the application plays a role effectively for the printing for biconvex part LC.

The printing equipment 11 of present embodiment can use biconvex part LC as record-paper P.Figure 21 is the key diagram of the schematic configuration that biconvex part LC is shown, Figure 20 cuts off sectional view seen by biconvex part LC along main scanning direction.Biconvex part LC has the plate shape biconvex lens LR of lenticular body R1 ~ Rn (n is the integer of more than 2) parallel arranged.Other lenses body R1 ~ Rn-1 except the lenticular body Rn configured at end RE2 is formed as, and the width (lens width) of left and right directions is for roughly the same width W 1 and the roughly uniform semi-cylindrical shape of form accuracy.The mode that the lenticular body R1 configured at the end RE1 of biconvex part LC mates with end RE1 with recess configures.At the lenticular body Rn that the end RE2 of biconvex part LC configures, as illustrated by the dotted line in figure, the shape that the part for lenticular body R1 ~ Rn-1 is short of, and formed by the lens width W2 narrower than the lens width W1 of lenticular body R1 ~ Rn-1.That is, lenticular body Rn form accuracy for lenticular body R1 ~ Rn-1 is low.In biconvex part LC, the face RS (Jimo liquid absorbed layer 96) of the opposition side of the male and fomale(M&F) of biconvex lens LR is directly printed with the image of parallax.User, by observing via biconvex lens LR the image printed out, can regard the image printed out as relief image.

In addition, a side end RE1 and end side RE2 of the main scanning direction of biconvex part LC is asymmetricly formed.Specifically, as shown in figure 21, part shortcoming (shown in Reference numeral 97 part) of RE2, thus, end RE1 and end RE2 becomes asymmetrical form.This notch part 97 becomes mark (identification tag), when being recorded by printing equipment 11, when the end face (being end RE1 in the present embodiment) making the end face of side namely should become benchmark is unanimously to correct direction, can easily and reliably carry out record, its result, more reliably can obtain good record result.

In addition, as an example, notch part 97 is formed as being the angle of 45 ° relative to main scanning direction and throughput direction.As long as that is, user can identify become benchmark end RE1 in which side, notch part 97 is what shape, position, size can.

In addition, the entirety forming the Scissoring device of biconvex part LC (cutting, stamping-out) omits diagram, but figure 22 illustrates the blanking die 200 when being got off from biconvex part P0 (sheet becoming the raw material of biconvex part LC larger than biconvex part LC size) stamping-out by biconvex part LC.The biconvex part LC that the present embodiment relates to is rectangle, so blanking die 200 is also copy the rectangle of this shape and comprise 4 cuttves to form four limits of (stamping-out) biconvex part LC.Reference numeral 201 and 202 forms 2 cuttves relative in above-mentioned 4 cuttves.Other 2 cuttves omit diagram in fig. 22.

In fig. 22, with Reference numeral g1 ~ gr, each lens are shown, the biconvex part LC after stamping-out is depicted as the component be made up of the lens of g3 ~ gr-2.That is, the lens Rn of the lens g3 of Figure 22 to be the lens gr-2 of the lens R1 of Figure 20, Figure 22 be Figure 20.

As shown in figure 22, in blank operation, on the main scanning direction of Figure 22 by involutory for cutter 201 position between adjacent lens g2 and lens g3, then stamping-out.

That is, in the present invention, accurate management enters just in time involutory position between the trench of adjacent lens gk to make shearing knife (for cutter 201 in Figure 22), and the cutting face of having carried out after cutting becomes the end RE1 of Figure 20.In fig. 20 end side RE2 be imprecision management cutting position (position of not carrying out shearing knife is involutory) cutting time section.

Therefore, as shown in figure 20, the thickness h 2 of lens jacket 93 located than end RE2 of the thickness h 1 of the lens jacket 93 at end RE1 place is thin.In addition, except lens jacket 93, the thickness of other each layers is uniform, so the thickness of end RE1 entirety becomes thinner than the thickness of end RE2 entirety.

In addition, the width w1 forming the lens R1 of end RE1 is larger than the width w2 of the lens Rn forming end side RE2, and the width w1 of lens R1 is suitable with the width (w1) adjacent to the lens R2 of these lens R1.In addition, the width of the other lenses Rk beyond end is w1.

That is, as long as critically manage cutting position during formation one side end RE1, without the need to managing cutting position when forming end side RE2 closely.Therefore, it is possible to suppress the complicated and cost increase of Scissoring device, and then the cost increase of biconvex part LC can be prevented.

In addition, from the meaning of the complicated and/or cost increase of suppression Scissoring device, although only tightly manage RE1 to carry out cutting, but sometimes according to the environment (temperature and/or humidity etc.) during cutting, biconvex part P0 can expand more or less and/or shrink, so cutting is carried out like that in the cutting position that also may manage RE2 in the same manner as management RE1.

And, about this biconvex part LC, if the end RE1 that formed can be cut off for benchmark is to carry out record with precision, then the situation that the image that should be recorded in a lens Rk is recorded across adjacent other lenses can be prevented.That is, in the example of Figure 23, the image of (1) ~ (8) all correctly can be received into lens R1, good visual effect can be obtained.

In addition, when printing, by edge 82A being detected with the 2nd sensor 75, and the starting position of specific printing.Now, balladeur train 22 also can be made to scan and notch part 97 be detected by the 2nd sensor 75.By like this, can prevent because user gets the mounting of biconvex part LC wrong towards caused misprint.Namely, when printing beginning when detecting notch part 97 by the 2nd sensor 75, can judge that the mounting direction of the biconvex part LC imagined is reverse relative to throughput direction, so, even if when biconvex part LC is reversed mounting relative to throughput direction, if make the direction that starts to discharge black liquid reverse relative to main scanning direction, then can print from the RE1 of end, the lifting of press quality can be realized.In addition, when having loaded biconvex part LC because of user along the opposite way round, also can notify that user makes it again load biconvex part LC.In addition, also can not rely on and detect notch part 97, but when printing biconvex part LC, in advance to the mounting direction of user's broadcast announcement biconvex part LC.

In addition, if the width of end RE1 and end RE2 is compared, its precision of end RE1 higher (by managing closely) that then width is wide, so, such as also can be detected the width of the lens being positioned at each end by the 2nd sensor 75, print from the end residing for the lens that precision is high.
